The invention has `for its object a dispenser for pulverulent or pasty substances, such as face powder, powdered soap,'soap paste and the like. I

Prior devicesfor this purpose," commonly comprise a container from which the pulverulent material may ow through 4small apertures formed in the upper or lid portionof y the container. One great disadvantage in- 10 herent in constructions of this kindis that the material dischargedgthrough the aperf tures has a tendency to settle toward the periphery of the container, causing escape and loss of material when the powder puifis 5 manipulatedto pickup the material.

f The invention will be best understood `from the following description when. read in the light of the accompanying `drawingsof a specific embodiment of the'invention selected for illustrative purposes,v the scope` of which `in-v "0 ventionv will be more particularly pointedout in the vappended claims. In the drawings i f Fig. l is a diametricalvertical section of a powder box constructed according to the in-l vention; d 'd' Fig. 2 is a plan ofthe powder box, according to Fig. 1, with the lid open and thepowder tray removed; i y Fig. 3 illustrates a detail of the powder box r according to Figsil and 2;`

Fig. 4 is a fragmentary viewfillustrating modification of the powder box according to ig.1; n y Fig. 5 is a planview of the parts shown by d Fig. 4; and ,Fig. 6 is a fragmentary 'section'corresponding to Fig. 1 showing a modification. d

The powdervbox illustrated by Figs.` 1 and 2 comprises a lower compartment 1 which contains the pulverulent 9; other materia;i

and is provided.axia-lly'thereof with avertitically disposed `conveyer screw2 which at its lower endl is rigidlyv fastenedto the bottom wall of this lower compartment, so that when theilatter is rotated relative to the upper com-` r partment'of the boxthe screw Vwill act to raise I and discharge,materialfromsaid ylower com partment into saidupper compartment. L As shown, the device comprises an annular member tov which thelid 5 of the box is hingedly connectedfat 4; Carried by this ,a`n

nular membery is a tray 22 havingaperipheral flange 23 which snugly engages the .inner 4 walls of the annular member. As shown, the tray22 forms the bottom wallof the upper compartment andthe ,top wall of the lower compartment. Removal of theltray from en gagementwith thelannular member Bfwill permit the lower compartment'tobe charged with material, and in this sensev the `tray yconstitutesaremovable lid for the lower compartment, said lid being normally held rin position dueto its snugiitwith theannular member 3. The annular. lateral wall ofthe lowercompartment 1 atitsupper edge is` pro-l vided with an inturned'annular flange 21`in engagement withv acircular slot formed aboutk the lower portion of the outer wall ofthe an-v nular 4member 3 to permity said lower come partment 4tobe rotated relative tothe upper compartment.

' `InteriorlyV of the lower compartment l is a cylindrical casing12-which vsurrounds the screw 2 this casing being secured tothe annular member 3 in nonrotatable relation therewith by radial arms 9 secured to the under side of the annular member at 8. 1' Thev tray` 22y is provided with an axial opening which registers withthe upper/wall 10ofvthe l casing 12, said upper wall being provided with orifices 11 for discharge ofthe material from the d, casing 12 to theupper compartment..

At its lower endthe casing12 is provided with one or morelateral openings tol permit the pulverulent or otherniaterialin the cornf partment 1 to enter said c'asingf In the present embodiment of thisv invention but one .of suchopeni'ngs is shown, andcommll' 1 meeting with'this @peeing is@ .Scoop-shaped parthaving a top wall 13, an outer wall 42, and a radialwall 19, there being no radial wall opposite the latter so as to provide an opening into which the material may be scooped as the casing 12 is rotated relative to the compartment 1. As shown, cooperating e with l thel scoop-shaped ypart just referred to is a bell crank lever 16 pivotally supported on aV shaft V15, which latter at its upper end is pivotally supported in oneof the arms), and at its lower end ispivotally supported on they horizontal leg ofan angle bracket 14.- rigidly carried by said arm, the. shaft having a torsion spring 20 normally holdin@ the bell crank lever in the position shown yi Fig.` 2l

of the drawings, The bell v crank lever, lwhich, is formed of spring material, has an arm 18 whichentersvthe scoopshaped part referred to, the outer endv of the arm l'bein'g iny closely adjacent relation to the inner side ofthe radial wall 19 of said member. The other arm. 17 of the bell crank` lever vis sliding contact vwith a strip 6 secured to the innerw side of the annular wal'lsof the lower compartment 1 ,Ythis strip having inwardly projecting. .curvilinear portions 7 which serve as cams for swinging the arm 18 of the' bellcrank lever toward the casing 12 as .the lower compartment 1 is rotated relative to the upper compartment, and serving both to guide the material ktoward the scoop-shaped part referredY to. and force the material caught by said scoop-shaped partinto the interior of the casing V12,and thus feed it to the Vrotatingv screw 2. l In the modification of the invention shown by Figs. 4 and 5, the upperi side of the 'top wall 10 of the ,casing yl2 is' preferably lined with a layer 25 of velvet, chamoisfor the like, secured thereto. in any convenient way.

asby tubular eyelets 27 extending., through partinent.. By this construction the screw 22 cannot be rotated relative to the casing 12 when the lid of the box is closed.

Having now particularly described and ascertained the nature of my invention, what I desire to secure by Letters Patent. is as follows :f

2. A device of the character described having, in combination, a container having a relatively rotatable apertured closure part, conveyor means within said container responsive.y to ,said relative rotation` for discharging pulverulent material from said' container through the aperture ofsaid closure part,
